Product and process for highlighting and streaking hair

Abstract

Liquid-impermeable sheets, suitably composed of aluminum foil, are provided with a coating of pressure-sensitive adhesive, preferably adjacent one edge of the sheet, and optionally, a strippable cover to protect the adhesive prior to use. The process comprises separating a portion of hair to be treated from the remaining hair on the head, adhering one of the liquid-impermeable sheets to the scalp and hair of the head immediately adjacent and below the roots of the portion of hair to be treated, and treating the selected portion of hair with any desired liquid-treating agent such as a bleach or dye and permitting the treated hair to overlie the central portion of the liquid-impermeable sheet while the treating agent takes effect and, optionally, folding or rolling the sheet toward the head and then folding the edges inwardly to form an envelope, thus isolating the treating agent from the remainder of the head of hair and treating only the selected portion of hair.

What is claimed is: 
     
       1. A liquid-impermeable imperforate sheet adapted to be removably secured to the scalp so that one edge is positioned closely adjacent the roots of selected strands of hair to be colored or bleached, a pressure-sensitive adhesive along only said one edge capable of adhering firmly but releasably to skin and hair and having substantially greater adhesion to said sheet, said sheet being of a thin, flexible metallic material capable of being folded and crimped to form a self supporting compact enclosure for said strands of hair to be treated, said enclosure retaining its folded configuration due to the crimping of said sheet by application of pressure alone. 
     
     
       2. A liquid-impermeable sheet of claim 1 wherein the coating of pressure-sensitive adhesive is provided by application to said sheet of an element comprising an intermediate backing coated on both sides with said pressure-sensitive adhesive. 
     
     
       3. A liquid-impermeable sheet of claim 1 wherein the adhesive coating not adhered to the liquid-impermeable sheet is protected prior to use by a strippable cover. 
     
     
       4. A liquid-impermeable sheet of claim 3 wherein the strippable cover extends beyond the adhesive area to provide a non-adhered tab to facilitate removal of said cover. 
     
     
       5. A liquid-impermeable sheet of claim 1 wherein the sheet is composed of aluminum foil. 
     
     
       6. A liquid-impermeable sheet of claim 1 having on the surface thereof opposite the adhesive coated surface, a coating of a hair treating agent, said coating of hair treating agent extending over the major portion of said surface except for uncoated areas adjacent those edges of said sheet other than the edge having the adhesive coating on the other side which edge is coated with said treating agent. 
     
     
       7. A liquid-impermeable sheet of claim 6 wherein said treating agent is in the form of a relatively dry gel activatable by application of a liquid to become an active hair treating agent. 
     
     
       8. A liquid-impermeable sheet of claim 1 wherein said adhesive area adjacent one edge of said sheet is spaced inwardly from the ends of said edge leaving adhesive-free sides on said sheet. 
     
     
       9. A liquid impermeable sheet of claim 8 including a strippable cover overlying said adhesive and extending beyond said area to provide a free tab for removal thereof.
